CHARLES A. DORAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO BAUER & BLACK, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

WASHER-SATURATING- MACHINE.

Application filed April 1,

T 0 all whom it may concern:

Be it known that I, CHARLES A. DURAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinios, have invented certain new and useful Improvements in Washer-Saturating Machines, of which the following is a specification.

This invention relates to a washer saturating machine in which gauze fabric or other material is treated preliminary to bleaching.

It is the object-of my invention to provide a machine through which a strip or sheet of gauze fabric or other material is continuously advanced, being first saturated with water or other liquid and subsequently relieved of its excess moisture, after which it it is delivered from the machine to the kiers for bleaching.

. Further objects and advantages of my invention resides in the various combinations hereinafter described as will be apparent as the same is better understood by reference to the following specification, when read in connection with the accompanying drawing illustrating the preferred embodiment thereof, in which- Figure 1 is a plan view of the machine;

Fig. 2 is a front elevation thereof, partly broken away for better illustration;

Fig. 3 is a section on the line 3-3 of Fig. 4; and

Fig. 4 is an end elevation of the machine partly broken away.

Referring to the drawing, 5 indicates a receptacle or vat preferably constructed of wood reinforced at the ends by frames 6, the lower ends of which provide legs" 7 to support the receptacle.

Two shafts 8 and 9 journaled in bearings 10 on the frames 6 support rolls 11 and 12 within and adjacent the top ofthe receptacle. Two shafts 13 and 14 are similarly journaled in bearings 15 on the frames 6,

and support rolls 16 and 17 within and adjacentthe bottom of the receptacle. The shaft 9 is provided with fast and loose pulleys 18 and 19 respectively which may be driven through a belt 20' from any suitable source of power, a shifterfork 21 being provided to permit adjustment of the belt to either pulley. A pulley 22 on the opposite end of the shaft 9 is connected by a belt 23 to a pulley 24 on the shaft 14. Thus the shafts 9 and it may be driven at will from Specification of Letters latent.

the source of power. Obviously other driving means than that described may be employet.

Within and adjacent its bottom, the receptacle 5 is provided with a plurality of baffle plates 25 secured to opposite side walls of the receptacle and extending above the normal surface of the liquid in the receptaole, as determined by the liquid outlet 26 in one end of the receptacle. An inlet 27 for the liquid is provided at the other end of the receptacle. The baffles 25 are provided with suitable openings through which the rolls 16 and 17 pass. The object of the baffles is to cause the liquid to follow a tortuous path as it flows from the inlet 27 to the outlet 26.

Mounted in frames 28 and 29 adjacent the rolls 11 and 16 are a plurality of guide rings 30 and 31 preferably of porcelain to guide the strip of fabric from the rolls 12 and 17 on to the rolls 11 and 16. As will be readily understood by reference to Fig. 4: the strip or sheet of gauze enters the top of the receptacle, passes down under the roll 16 at one end thereof, thence over the roll 17 and back through one of the ring guides 31 to the roll 16. Thence it continues in a zigzag direction back and forth between the rolls to the opposite ends thereof. During this movement the strip or sheet of fabric is submerged in the liquid and is washed and thoroughly saturated therewith. From the roll 17 the strip or sheet of fabric, as will be readily seen by reference to Fig. 2, passes upwardly to the roll 12 and thence through one of the ring guides 80 to the roll 11. The strip or sheet of fabric passes in a zigzag direction back and forth between the rolls 12 and 11 to the opposite ends thereof, where it leaves the receptacle as indicated in Fig. 4. Duringthe movement of the strip or sheet of fabric'over and between the rolls 11 and 12 the excess liquid is removed therefrom by centrifugal force and the squeezing action as the material passes over rolls 11 and 12 leaving the fabric in proper condition for further treatment in the bleaching kiers. The rolls12-and 17 being driven from the source of power as hereinbefore described the fabric. may be drawn through the machine continuously at a relatively high rate of speed.

From the foregoing it will be readily understood that I- have perfected a machine for washing and saturating strips or sheets of fabric and similar materials which is capable of handling large quantities of material in a relatively short time and may be operated continuously to saturate and remove the surplus water from the fabric. The machine is particularly designed for handling strips of gauze bandage and a dimcult problem in the handling of this class of material is solved by the use of my machine.

Various changes may be made in the form, construction and arrangement of the parts without departing from the spirit or scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely the preferred embodiment thereof.

I claim:
